DEVICE FOR ATTACHING TELEPHONE AND OTHER WIRES TO INSULATORS.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed March 23, 1905. Serial No. 251,680.

To all, whom it may concern:

Be it known that we, Esnx IVICDANIEL and MICHAEL BARR, citizens of theUnited States, residing at Paris, in the county of Edgar and State ofIllinois, have invented certain new and useful Improvements in Devicesfor At taching Telephone and other WVires to Insulators; and we dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in insulators, particularly withreference to devices for connecting telephone, telegraph, and otherwires thereto, the object of our invention being to provide an improveddevice of this character by means of which a wire may be readilyattached to and disconnected from the insulator and is renderedlongitudinally movable with reference thereto to relieve the wire ofundue stress; and our invention consists in the construction,combination, and arrangement of devices hereinafter described andclaimed.

1n the accompanying drawings, Figurel is a side elevation of aninsulator provided with a wire-attaching device embodying our improvements, the wire being shown in section. Fig. 2 is a similar view atright angles to Fig. l, the wire being shown in elevation; and Fig. 3 isa horizontal sectional view through the insulator on a plane coincidentwith the wire-attaching device, showing the latter in top plan. Fig. 4is a detail view showing a modification in the construction of the pin.

The insulator 1 here shown is of the usual form. The same is providedwith transverse annular grooves 2. Our improved wire-attaching device 3is formed from a single piece of wire, which is doubled, as at a,twisted, as at b, to form a loop a, and has its end portions d passedaround the annular grooves in the insulator and united together bytwists 0, so as to secure the device firmly to the insulator. The loop 0projects outwardly from the insulator and is bent downwardly andinwardly to form an angle f, the bend a, which forms the outer end ofthe loop, being caused to approach the insulator. In operation the wireg is placed in the angle f of the loop, and a pin /b is then passeddownwardly in the loop on the inner side of the wire and caused toengage the two ends of the loop, so as to lock the wire in the angle fthereof. The pin,

which may be made of wire or any other suitable material, is providedwith the hook t' to engage one side of the upper portion of the loop toprevent casual disengagement of the pin from the device.

It will be understood that the wire may be very readily attached to anddetached from the device, that there is no necessity for passing thewire around the insulator, as is now the common practice, and it will befurther understood that the wire slidably engages the loop 0, so thatthe wire becomes balanced on opposite sides of the insulator, andinjurious and lateral stress is thereby avoided. If it be desired tolock the wire to the attaching device, so that it cannot movelongitudinally therein, this may be accomplished by first bending thepin it before inserting the same and then partly turning the same todispose its convex side against the wire, so that the pin acts as awedge to lock the wire in the angle f of the loop.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is*

A wire-attaching device for insulators, comprising a wire band, adaptedto be bent around the insulator, said band being twisted to form a loopat one side, said loop projecting outwardly from the insulator and bentdownwardly and inwardly to form an angle, the band at the outer end ofwhich approaches the insulator, in combination with a wire disposedtransversely with respect to the loop and in said angle thereof, and alocking-pin on the inner side of the wire and engaged with the upper andlower ends of the loop, said pin having a hook at its upper end toengage the upper portion of the loop.

In testimony whereof. we have hereunto set our hands in presence of twosubscribing witnesses.
